1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeGastrointestinal nematodiasis is a significant challenge in small ruminant breeding. The present systematic review and meta-analysis shed light on the frequency and distribution of the infection in a nationwide perspective.

methodsThe review used 34 animal level datasets retrieved from 26 published articles and the pooled estimates were calculated using a random-effects model analysis.

resultsAltogether, 9690 small ruminants were examined post-mortem or by coproscopy, among which 4193 animals were infected with GINs, showing a weighted prevalence of 55% (95% CI 44-66%). Reports were documented in 12 provinces with the highest frequency in Eastern Azerbaijan (77%), Kermanshah (76.04%), and Guilan (71.62%). Moreover, the highest prevalences were estimated among goats [61% (95% CI 48-74%)] and in coproscopy [67% (95% CI 57-78%)]. The reported GINs represented 15 genera, including Haemonchus contortus, Marshallagia marshalli, Trichuris spp., Trichostrongylus spp., Ostertaginae species, Gongylonema pulchrum, Nematodirus spp., Parabronema skrjabini, Skrjabinema ovis, Chabertia ovina, Cooperia punctata, Camelostrongylus mentulatus, Bunostomum trigonocephalum, and Oesophagostomum venulosum. The most isolated nematode species in sheep and goats belonged to H. contortus [7.44% (95% CI 6.78-8.13%] and Trichuris spp. [18.42% (95% CI 16.54-20.41%)].

conclusionA considerable parasitic prevalence was calculated in small ruminants in Iran, demanding strategic interventions for better control the GIN infections and decrease the worms burden and their consequences in sheep and goat population in Iran.
